Jogging stop mode A 39 N
When a stop command is issued during activated jogging mode,
the motor stops by:
00: running free
01: decelerating using configured deceleration time
02: decelerating using DC brake

DC braking
L2000 series inverters have a configurable DC brake that is activated as soon as the stop command is issued. By
applying a strobed DC voltage to the motor’s stator a braking torque is induced into the rotor that effectively works
against the rotation of the motor. Usage of the DC brake makes possible high registration accuracy when carrying
out positioning work.
CAUTION Usage of the DC brake causes an additional heating of the motor. For this reason the DC
brake should be configured with as short a braking torque and braking time as possible.
